Cheaper than a shotgun

We are talking "kill ratio"

Barb found mice droppings downstairs on Sunday and was focused on Armageddon.
I did a little research on this and concluded that a shotgun would cost over 30 dollars per 100 mice (just for the shells). 
Here I get the unit and the batteries for just over 22 dollars for 100 mice.

I'm going for this and I don't have to repair the walls after I'm done.
